Simple sonic animation js version

I need a simple js waveform animation. I found several that draw lines, but I need one that draws squares, so I wrote one by hand.

The effect is as follows:

setInterval(() => {
    
    
  for(let i = 0; i < 10; i++) {
    
    
    let ele = document.getElementById(`item-${
      
      i}`)
    let height = 100 * Math.sin(Math.PI / 10 * i) * Math.random()
    ele.style = `transition: height 0.15s ease;height:${
      
      height}px;`
  }
}, 150);
